EcoFlow DELTA 1300 vs Allpowers R1500
Side-by-side on the specs that decide it — surge, capacity, runtime and price.
Both models' specs verified against manufacturer listings · Last updated
The short answer
Allpowers R1500 costs $300 less. Whether that gap is worth closing depends on what you need to run.
- EcoFlow DELTA 1300 holds 9% more energy (1260Wh vs 1152Wh), so it runs the same load proportionally longer.
- EcoFlow DELTA 1300 has 300W more surge headroom (3300W vs 3000W) — that decides whether a fridge, pump or AC compressor will actually start.
- EcoFlow DELTA 1300 is 6.6 lb lighter (30.9 lb vs 37.5 lb).
- Allpowers R1500 uses LiFePO4 while the other uses NMC — roughly double the usable cycle life.
- Allpowers R1500 is rated for 3,500 cycles vs 800 — meaningful if you cycle it daily.
If you plan to cycle the battery daily, think twice about the EcoFlow DELTA 1300. Its NMC cells are rated for 800 cycles against the LiFePO4 rival's longer life — over years of regular use that's the more expensive unit, whatever the sticker says.
The original DELTA that put EcoFlow on the map. Fast-charging and high-surge for its day, but the NMC battery and lack of USB-C now show its age.
Best for: Bargain hunters who find it heavily discounted.
Where it falls short:
- NMC — ~800 cycles
- No USB-C PD
- 2-year warranty
A well-priced 1.1kWh with a real 1,800W output and fast charging, a common budget pick for home backup starter kits.
Best for: First-time backup buyers who want 1,800W output cheap.
Where it falls short:
- 37.5 lb for 1.1kWh
- Not expandable
